    Unhappy 3G 3.1.2 unlock won't work!! 5.11.07
    iphone 3G
    3.1.2
    5.11.07 modem firmware

    JB using blackra1n
    Tried
    - installing snow through blackra1n app
    - tried installing blacksnow through cydia
    - uninstalled blacksnow and tried ultrasn0w

    all install but when I put in my gf's t-mobile SIM into the iphone it
    search's for a network
    then says "Could not activate cellular data network"
    and then finally it says "locked sim"

    I've tried hard rebooting and reseting network settings many of times and everytime it comes back with "locked sim"

    is it the SIM? the SIM card works fine in her tmobile blackberry...

    i do get some refressh and bzip2 errors when installing blacksnow or ultrasn0w but they both do install after i hit ok to those errors

    what do i do?

    3G is turned off though = / ...it wasn't when i first "unlocked" it but after i did i turned 3G off

    Now, do i restore back to a factory 3.1.2 or 3.1.3 and re-jailbreak? If so, how do i rollback to those versions?

    Otherwise just jailbreak over the jailbreak again? I did do that but with blackra1n...

    thanks so much!

    haven't been able to track down a non at&t/verizon person with a regular nonmicro sim = /


    so do i have to restore back to factory 3.1.2/3 and re-jb/unlock?
